Dear Steven and others, I have a problem about Scheme. When I do a loop in the meep just like this: (do ((deg 30 (+ deg 0.2)))((> deg 40))(print deg "--"))
the result is strange: 30--30.2--30.4--30.6--30.8--31.0--31.2--31.4--31.6--31.8--32.0-- 32.2--32.4--32.6--32.8--33.0--33.2--33.4--33.6--33.8--34.0--34.2-- 34.4--34.6--34.8--35.0--35.2--35.4--35.6--35.8--36.0-- 36.2000000000001--36.4000000000001--36.6000000000001-- 36.8000000000001--37.0000000000001--37.2000000000001-- 37.4000000000001--37.6000000000001--37.8000000000001--38.0000000000001-- 38.2000000000001--38.4000000000001--38.6000000000001--38.8000000000001-- 39.0000000000001--39.2000000000001--39.4000000000001--39.6000000000001-- 39.8000000000001-- Why there so many 0000000000001 at the end? and How can I avoid them? Thank you very much :)
